High harmonic generation in rhombus graphene quantum dots with elliptically polarized strong laser pulses
Abstract
Abstract In this paper, we studied the transformation of light in a rhombus graphene quantum dot during the generation of high harmonics in an intense laser field of elliptical polarization. The linearly polarized laser field leads to intense emission of elliptically polarized harmonics and vice versa. The ellipticity and orientation of the polarization ellipse are derived from the Stokes parameters calculated by considering various polarization components. Numerical results show that the ellipticity of harmonics generated in a quantum dot can be easily tuned by adjusting the tilt angle of the polarization vector of the elliptically polarized laser pulse, eliminating the need for complex control systems.
